Abstract

<P>PROBLEM TO BE SOLVED: To provide a passenger conveyor safety device having simply formed steps, capable of proving excellent manufacturability and field installability, and capable of increasing safety. <P>SOLUTION: This passenger conveyor safety device comprises a movable part 6 projected from step faces and vertically extended and retracted therefrom when a passenger carelessly approaches the end edge part of a step 12 and a movable cam 7 coming into contact with the lower end of the movable part 6 and horizontally movable when the movable part 6 moves vertically. A plurality of detection switches 8 opposed to the movable cam 7 are disposed at positions opposed to the side face of the step 12 at specified intervals. The device also comprises an alarm means which receives the operating signals of the detection switches 8 and emits alarm. Thus, a passenger can be prevented from being caught between the step end edge part and a skirt guard by the simply formed step. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

    The present invention relates to passenger conveyor safety devices such as escalators and moving walkways.

    Conventionally, in order to prevent passenger clothes and luggage from being caught in the gap between the step and the skirt guard, a demarcation cleat with a changed material and color of the step edge and the height of the edge has been provided. Raised attention to passengers.

In addition, in order to eliminate the drawbacks of this structure, in passenger conveyors such as escalators and moving walkways, a load detection means is provided at the edge of the step, and an attention signal is given to the passenger by an operation signal from the load detection means. There has been proposed a safety device including an informing means for performing the operation (see Patent Document 1).
JP-A-5-338980 (page 2, paragraph number 0088, FIG. 2)

  The above prior art has the following problems to be solved.

  1. In order to send an operation signal of the limit switch from the movable step to the stationary frame side, it is necessary to attach an operation signal conducting rail separately from the step rail.

  2. The operating signal conducting rail must be completely insulated in the frame.

  3. In order to transfer an operation signal between the movable step and the conductive rail, a member that moves around the conductive rail and the step is required. For this reason, work at the time of maintenance and inspection, such as confirmation of the degree of wear and operation status, is essential.

  An object of the present invention is to install a switch for detecting an operation signal on the frame side, so that it is not necessary to receive an electric signal between the step and the switch, and the passenger conveyor has a simple structure that does not require insulation from the step or the rail. It is to provide a safety device.

  In order to achieve the above-mentioned object, the present invention is such that a movable part that protrudes from the tread surface at the edge of the step and enters and exits in the vertical direction, abuts the lower end of the movable part, and moves horizontally when the movable part moves up and down. A movable movable cam is provided, and on the other hand, a plurality of detection switches facing the movable cam are arranged at intervals in a position facing the side surface of the step, and a warning is issued in response to an operation signal of the detection switch. An informing means is provided.

  In passenger conveyors such as escalators and moving walkways according to the present invention, even if a passenger inadvertently approaches a step edge, a warning message is immediately issued to alert the passenger of the step edge. The foot is moved from the center to the center, and the step edge portion and the skirt guard can be prevented from being caught.

  According to the present invention, a large number of steps are connected endlessly, and in a passenger conveyor such as an escalator or a moving sidewalk that runs endlessly with one of the entrances and exits, the end edge of the step protrudes from the tread surface, and vertically And a movable cam that comes into contact with the lower end of the movable portion and is movable in the horizontal direction when the movable portion moves up and down, and is opposed to the movable cam at a location facing the side surface of the step. A plurality of detection switches are arranged at intervals, and an alarm is issued when a passenger gets unconsciously on the edge of a step, and is provided with a notification means for issuing a warning in response to an operation signal of the detection switch. By providing passenger safety information such as escalators and moving walkways that prevent passengers' clothing and shoes from being caught in the gap between the steps and the skirt guard by notifying passengers of danger It can be.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a cross-sectional view showing a configuration of an embodiment of a passenger conveyor safety device of the present invention, FIG. 2 is a cross-sectional view of a step end edge portion, and FIG. 3 is a view as seen from the top of the step end edge portion.

  In a passenger conveyor such as an escalator or a moving sidewalk where a number of steps of the present invention are connected endlessly and run endlessly between one entrance and the other exit, as shown in FIG. 1. Rail for moving handrail 2, panel 3, deck 4, skirt guard 5 fixed to deck 4 at a predetermined distance from step 4, step 12, demarcation cleat 13 of step edge at step edge A movable part 6 is attached that is the same as the total length of the movable part 6 and that is movable up and down to detect that the passenger has approached. As shown in FIG. A movable cam 7 is provided that protrudes laterally.

  The frame 14 is provided with a detection switch 8 for detecting the protrusion of the movable cam 7, and includes a broadcast control device 15 for calling attention by an operation signal of the detection switch 8, and a notification means constituted by a speaker 16 for issuing an alarm. ing.

  Since FIG. 3 is a view of FIG. 2 as viewed from above, description thereof is omitted.

  The operation of the passenger conveyor having the above-described configuration will be described below.

  If the passenger unconsciously gets on the demarcation cleat 13 at the edge of the step during the passenger conveyor operation, the movable part 6 in the demarcation cleat 13 is pushed down the step.

  In conjunction with the lowering of the movable portion 6, the movable cam 7 projects toward the reframe 14 side from the step side surface.

  When the movable cam 7 protrudes and reaches the position of the detection switch 8 fixed to the frame 14, the detection switch 8 is operated, and an operation signal from the detection switch 8 is transmitted to the broadcast control device 15, and the broadcast control device. A warning message or the like is issued from the speaker 16 according to the instruction 15 to inform the passenger of the danger.

  Accordingly, the passenger can prevent clothes, shoes, luggage, and the like from being caught between the step 12 and the skirt guard 5 by moving shoes and luggage from the edge of the step toward the center.

  Further, since the time during which the shoes and luggage are in contact with the skirt guard 5 can be shortened, it is possible to prevent the shoes and luggage from being drawn into the step 12 and the skirt guard 5 and being pinched.

  Here, it is possible to notify the danger earlier by attaching a large number of detection switches 8 attached to the frame 14 in the vicinity of the landing.

It is sectional drawing which shows the structure of one Embodiment of the passenger conveyor safety | security apparatus of this invention. It is sectional drawing seen from the back of a step end edge part. This is an enlarged view of the step edge from the top.
